About wall plugs and screws for plasterboard

Types of wall plugs and screws for plasterboard

Plastic wall anchors

Plastic wall plugs are a frequently used type considered to be compact, economical, and easy to mount. They are meant for lighter loads and are ideal for mounting small items like picture frames and mirrors. These plugs are quite adaptable and can be used with screws of various materials. Plastic wall anchors come in many colors and sizes, so users can choose the best-fitted one for the task.

Metal wall anchors

Metal wall plugs are robust and effective anchoring devices used to hold heavy paintings, shelves, and other items on plasterboard constructions. Due to their metal construction, they are suitable for heavy-duty applications. They have good strength and can maintain longer materials than plastic ones. Some come with self-piercing screws, whereby no pre-drilling is needed.

Screw-and-anchor combinations

Certain manufacturers produce screws and anchor combinations specially designed for plasterboard walls. These anchors are made to distribute the load more uniformly and often have a unique design that permits expansion or locking as the screw is driven. Such a design improves the screw's grip and attachment on the wall. Such combinations are especially useful in hanging heavy items such as cabinets, mirrors, etc.

Toggle clamps

Toggle bolts are excellent hollow wall anchors that work perfectly on plasterboard walls. These anchors consist of a wingspread metallic anchor that folds as a screw is inserted through it. Once the toggle bolt is fitted through the wall and placed in a cavity behind the drywall, the wings open out and provide a large load-bearing surface. This makes toggle bolts ideal for hard-wall hanging items, including large mirrors, TV mounts, shelves, etc. Though larger than other anchoring types, they must be heavy-duty anchoring devices and use effective toggles.

Expansion plugs

Expansion plugs are larger and more rigid plastic anchor varieties. These anchors are designed for use with concrete or brick walls, but a few can be installed into drywall with a penetrating core. The plug expands when a screw is added, allowing it to form a tighter fit with the screw. This makes them suitable for holding heavier items such as shelves.

Industrial and Commercial Applications of Plasterboard Wall plugs and screws

ù

Drywall finishes

These screws are used to attach drywall to steel or wood studs. Gypsum boards are fixed quickly and easily this way, making the process simpler. Their fine threads provide a secure hold, ensuring a flat surface when the wall is finished.

Tile backer boards

Tile backer boards are drywall sheets that feature waterproofing and insulation capabilities and are used under tile work in bathrooms and kitchens. Wall plugs and screws for plasterboard hold these boards in place to other studs or framing. This offers a stable and level base for tile installation. The screws are corrosion-resistant so that they will not rust when wet.

Suspended ceilings

Drywall screws help fix plasterboard to suspended ceiling grids, also called drop ceilings. The use of these screws makes hanging ceiling tiles easy and quick. It supports the tiles' weight within the grid framework of the ceiling. Using such screws maintains a level and neat ceiling finish.

Paneling and decorative ceilings

These screws are suitable for installing decorative paneling and ceiling features such as coffered or vaulted ceilings. They provide a secure way of attaching panels to the framing underneath. Their low profile heads minimize the visible hardware on the paneling, thus giving a finished look.

Access panels and openings

Wall plugs and screws are involved in the installation of access panels in the drywall, allowing easy electric and plumbing access. They fasten the frame of the panel correctly to the drywall, ensuring stability. This anchor system provides a proper-fitting door that can be easily opened and closed.

Product Specifications and Features of Plasterboard wall plugs and screws

Technical specifications

  • Material: Plasterboard wall anchors are made from nylon and other variants, which ensure both durable and flexible anchoring. Metal toggle anchor bolts are fashioned from corrosion-resistant steel for heavy-duty anchoring.
  • Load capacity: Light-duty anchors range from 15-20lbs, while heavy-duty ones can go up to 100lbs, depending on the type and the manufacturer.
  • Sizes: The diameter generally lies between 3-8mm, while the length lies between 25-50mm. Toggle bolts can be longer if needed.
  • Finishes: Screws are usually plated with zinc or chrome to prevent rusting and improve the screw's overall aesthetics.

How to Install

  • Installing plastic anchors:Use a drill to insert anchors and screws. Insert the anchor into the wall after drilling; then, the screw is driven through the item to be hung into the anchor.
  • Metal anchors: The metal anchor is similar to a plastic anchor, except that the metal anchor will be fixed by screwing into the item to be hung after inserting the anchor into the wall.
  • Toggle bolts: The toggle bolt is folded and inserted through the drywall. After tightening, the toggle expands to form a secure anchor.

Maintenance and repair

  • Periodic checks: It is also advisable to check framed pictures, shelves, and mirrors periodically to see whether there is any sign of sagging or loosening.
  • Load redistribution: It is recommended that items be taken down and, if needed, their weight redistributed if several items hang on the same anchor.

Quality and Safety Considerations of Plasterboard wall plugs and screws

Use the correct type of plug and screw

Great attention should be given to selecting wall plugs and screws designed for the particular weight and type of item to be hung. Toggle bolts or heavy-duty metal anchors are warranted for heavier items such as mirrors and shelving units. A simple plastic or self-adhesive wall plug is suited for light fixtures, small frames, etc.

Corrosion-resistant materials

Anti-corrosion plugs and screws should be selected for use in areas constantly exposed to moisture, e.g., bathrooms and kitchens. Choosing screws made of stainless steel or with a weather-proof coating will help prevent rusting or deterioration.

Regular checks and maintenance

Periodic checks must be done on the fixtures so that they can be maintained at the right level of safety and security. Any sign of sagging, cracking plasterboard wall, or rusting will signal that appropriate measures must be taken to prevent any further deterioration.

Proper installation technique

It is important that wall plugs and screws be fitted in a manner that ensures proper safety. It means that the anchor should fit snugly into the plasterboard cavity and that the screw should be driven in flush with the surface. Over-tightening may lead to anchor failure, while under-tightening causes a lack of support. Using a level and measuring the height/width to place the item in a straight line will ensure proper installation precautions are taken.

Load limits

Avoid overloading wall plugs and screws. Follow the manufacturer's recommendations regarding the load-bearing capacity of the anchor hardware. The anchor may become dislodged and cause damage to the wall and the object it supports when overburdened.

Q&As

Q1: What wall plugs are suitable for use on plasterboard?

A1: The most suitable wall plugs for use on plasterboard are those with a cavity, such as expanding metal anchors, picture hangers, toggle bolts, and spring clips.

Q2: How are wall plugs installed in plasterboard?

A2: Wall plugs should be inserted into pre-drilled holes after the drywall has been attached to the studs and before the finishing work commences. Screws should then be driven through the plugs and the items to be hung.

Q3: What is the best anchor for a ceiling fan?

A3: A ceiling fan requires an electrical box rated for ceiling fans, which may be bolted to the ceiling joists or supported by anchors through the drywall to the box.

Q4: How many screws should be used when attaching drywall to studs or joists?

A4: The drywall should be secured every 8 inches along the stud and every 12 inches across, around, and through the field and at the ends of each drywall sheet.
